Description
The V6310 is a CMOS device which monitors the supply voltage of any electronic system, and generates the appropriate Reset signal. The g ap between the two thresholds defines the allowed voltage range. As long as V stays inside this voltage DD window, the output stays inactive. If V drops below V , or DD THlow rises above V , the output gets active. When V enters into THhigh DD the allowed range, the output remains active for an additional 50 ms (typ.). This allows the system to stabilize before getting fully active. The lower thresho ld voltage may be obtained in different versions:
2.0 V to 6 V
2.4 V to 6 V
2.8 V to 6 V
3.5 V to 6 V
4.0 V to 6 V
4.5 V to 6 V
